Abstract
The present description relates to a computer-implemented method, computer system, and computer program product for optimization of evaluation of a policy specification. In one aspect, the computer-implemented method for optimization of evaluation of a policy specification may comprise receiving the policy specification represented as a tree, the tree comprising a plurality of nodes. A visiting history of the tree may be determined by computing a density at least for each node in a subset of the plurality of nodes having been visited. The density may be determined by a relationship between a position of a node v in the tree and a frequency F(v) in which the node v is visited. The tree may be transformed with respect to the visiting history into a similar tree such that sibling nodes in the subset of the plurality of nodes are sorted in decreasing order according to their density.
